If the excitation of the shock absorber is greater, the control piston moves to its limit position so that oil ceases flowing through the bypass duct, meaning that the full damping force is available.
This article analyses the influence of the support of oil film vibration damping of the main spindle on cutting degree of roughness through cutting test.
